Answer: a) 0.070 moles of oxygen were produced.

b) New pressure due to the oxygen gas is 2.4 atm

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 2.7 atm

V = Volume of gas = 700 ml = 0.7 L

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = 329 K

$n=\frac{PV}{RT}$

$n=\frac{2.7atm\times 0.7L}{0.0821 L atm/K mol\times 329K}=0.070moles$

Thus 0.070 moles of oxygen were produced.

When the 700 mL flask cools to a temperature of 293K.

$PV=nRT$

$P=\frac{nRT}{V}$

$P=\frac{0.070\times 0.0821\times 293}{0.7}$

$P=2.4atm$

The new pressure due to the oxygen gas is 2.4 atm

I'm pretty certain the answer is 2) because fluorine is a diatomic gas meaning it travels with 2 molecules (simplified). It is a gas so molecules should also be spread out so the answer cannot be 3) or 4).

Hope this helps! :)
